La poesía de Luis Antonio de Villena: desde el gran estilo al realismo

I have resorted to several theoretic notions that had permited me to develop the thesis of the present article: the institutionalization of a contractual relation between writer and reader, in the spanish literary system. This relation shows a certain realism in Villena's writling program, which embraces the lyric bend 1971-1993. The notion of literature as system permits us see Villena's work in a lyric bend superstamped on the so called "estética novísima" and the poetry of the '80. The Villena's case results interesting because of the fact that the social personage interfuses with his other textuals subjects, in front of the great public, from a television set, or from a newspaper.He debido recurrir a una serie de nociones teóricas que permitieran desarrollar la tesis del presente trabajo: la institucionalización en el sistema literario español de una relación contractual entre autor y lector, relación a través de la cual se posibilita un cierto realismo en el programa escritural villeniano, que abarca la curva lírica 1971-1993. La literatura entendida como sistema permite ver la obra de Villena en una curva lírica sobreimpresa a la estética novísima y a la poesía de los '80, y con ello, las correlaciones de lo literario y de lo extraliterario El caso de Villena resulta interesante, porque su personaje social se imbrica con sus otros sujetos textuales, ya sea ante un gran público, ya sea desde la televisión o desde la columna periodística. Delimita así un campo mucho más amplio y complejo que el meramente textual, para la reconstrucción de una ideología

Cosmetics for acne: indications and recommendations for an evidence-based approach.

AIM: The aim of this review was to evaluate, by a thorough revision of the literature, the true efficacy of currently available topic and systemic cosmetic acne agents. METHODS: The efficacy of currently available cosmetic acne agents has been retrospectively evaluated via thorough revision of the literature on matched electronic databases (PubMed). All retrieved studies, either randomized clinical trials or clinical trials, controlled or uncontrolled were considered. RESULTS: Scientific evidence suggests that most cosmetic products for acne may enhance the clinical outcome. Cleansers should be indicated to all acne patients; those containing benzoyl peroxide or azelaic/salicylic acid/triclosan show the best efficacy profile. Sebum-controlling agents containing nicotinamide or zinc acetate may minimize excessive sebum production. Cosmetics with antimicrobial and anti-inflammatory substances such as, respectively, ethyl lactate or phytosphingosine and nicotinamide or resveratrol, may speed acne recovery. Topical corneolytics, including retinaldehyde/glycolic acid or lactic acid, induce a comedolytic effect and may also facilitate skin absorption of topical drugs. Finally, the use of specific moisturizers should be strongly recommended in all acne patients. CONCLUSION: Cosmetics, if correctly prescribed, may improve the performance of the therapy, whereas wrong procedures and/or inadequate cosmetics may worsen acne. Cosmetological recommendations may allow clinicians to make informed decisions about the role of various cosmetics and to indentify the appropriate indications and precautions. The choice of the most effective product should take into consideration the ongoing pharmacological therapy and acne type/severity as well

A protective role for autophagy in vitiligo

A growing number of studies supports the existence of a dynamic interplay between energetic metabolism and autophagy, whose induction represents an adaptive response against several stress conditions. Autophagy is an evolutionarily conserved and a highly orchestrated catabolic recycling process that guarantees cellular homeostasis. To date, the exact role of autophagy in vitiligo pathogenesis is still not clear. Here, we provide the first evidence that autophagy occurs in melanocytes and fibroblasts from non-lesional skin of vitiligo patients, as a result of metabolic surveillance response. More precisely, this study is the first to reveal that induction of autophagy exerts a protective role against the intrinsic metabolic stress and attempts to antagonize degenerative processes in normal appearing vitiligo skin, where melanocytes and fibroblasts are already prone to premature senescence

Release of Palladium from Biomechanical Prostheses in Body Fluids Can Induce or Support PD-Specific IFNγ T Cell Responses and the Clinical Setting of a Palladium Hypersensitivity:

The increased use of Palladium (Pd) for biomedical applications, which has more than doubled in the last ten years, appears to be associated with an increased frequency of adverse reactions to Pd. The aim of this study is to investigate the relationship between the implant of a biomechanical apparatus containing Pd and the setting of a hypersensitivity to Pd by determining the levels of the metal released in biological fluids, assessing the effects of Pd on peripheral blood mononuclear cell (PBMC) cytokine production and exploring the clinical setting of skin sensitization. Of a total of 3,093 subjects examined in 2006, sensitization to Pd alone or in association with nickel (Ni) was observed in 1.6% and 13.03% of the individuals, respectively. Of these, a group of six subjects positive to Pd and negative to Ni at patch testing were selected on the basis of the oral clinical symptoms in order to measure both the levels of Pd in biological fluids and the degradation of the dental prostheses. Specific Pd measurements were carried out on salivary fluid, urine and serum samples by High Resolution Inductively Coupled Plasma-Mass Spectrometry. In addition, the degradation of the dental prostheses was assessed by both a "leaching test" and an analysis of the micro morphology of orthodontic prostheses. The induction of IFN-γ production by Pd was assessed in PBMC by the ELISpot assay. Skin sensitization to Pd was evaluated by patch testing and clinical examination. Ten healthy subjects were comparatively tested as controls. We found a specific induction of an IFN-γ response by Pd in PBMC collected from all the subjects positive to Pd at patch testing. On the contrary, control subjects did not show any response to Pd as assessed by IFN-γ ELISpot assay or by skin testing. Remarkably, the levels of Pd in all biological samples (saliva, sera, urine) were significantly higher in Pd-sensitized patients than in those collected from controls, reaching the highest concentrations in the urine. The leaching studies gave additional evidence that the dental appliances can release measurable levels of Pd in saliva. Oral clinical symptoms in patients with Pd dental prostheses were associated with measurable levels of Pd in the biological fluids, the induction of Pd-specific IFN-γ responses in PBMC and the clinical evidence of skin sensitization to Pd. These data suggest that dental appliances may represent an active source of Pd in the body, and this, in turn, can favour the clinical setting of a hypersensitivity to this metal

Metabolic abnormalities associated with initiation of systemic treatment for psoriasis: evidence from the Italian Psocare Registry.

Objective To evaluate variations in laboratory parameters and diagnoses of selected clinical conditions up to16 weeks after starting a new systemic psoriasis treatment for Psocare Registry enrollees.Design Prospective cohort study.Setting Italian public referral centres for psoriasis treatment.Patients First-time recipients (n = 10,539) of continuous systemic psoriasis treatment for at least 16 weeks.Main outcome measure Mean variations in (weeks 8 and 16) and proportions of patients reaching a clinicallymeaningful increase in serum levels (week 16) of total and low-density lipoprotein cholesterol, triglycerides, aspartateamino transferase, alanine amino transferase and creatinine, as well as week-16 cumulative incidences of newdiagnoses of diabetes mellitus and arterial hypertension.Results Mean cholesterol and triglyceride levels significantly increased in patients treated with acitretin orcyclosporine. Mean triglyceride levels also increased in efalizumab- and etanercept-treated patients. Meantransaminase values increased in methotrexate-treated patients, and mean aspartate amino transferase levelsincreased in infliximab-treated patients. The average serum creatinine value increased in cyclosporine-treatedpatients. Acitretin and cyclosporine were associated with risk of hypercholesterolaemia (odds ratios 1.51 and 1.34)and acitretin with risk of hypertriglyceridaemia (odds ratio 1.43). Methotrexate and infliximab were associated withrisk of more than doubling the upper normal aspartate amino transferase (odds ratios 2.06 and 1.87) and alanineamino transferase (odds ratios 2.38 and 1.74) values. The relative risk of developing arterial hypertension anddiabetes was increased for patients receiving cyclosporine (odds ratios 3.31 and 2.88).Conclusion Systemic treatments for psoriasis resulted in heterogeneous effects on the parameters analysed.Received: 1 September 2011; Accepted: 12 January 201

Rome consensus conference-statement: human papilloma virus diseases in males

Human Papillomavirus (HPV) is a very resistant, ubiquitous virus that can survive in the environment without a host. The decision to analyse HPV-related diseases in males was due to the broad dissemination of the virus, and, above all, by the need to stress the importance of primary and secondary prevention measures (currently available for women exclusively). The objective of the Consensus Conference was to make evidence-based recommendations that were designed to facilitate the adoption of a standard approach in clinical practice in Italy. METHODS: The Sponsoring Panel put a series of questions to the members of the Scientific Committee who prepared a summary of the currently available information, relevant for each question, after the review and grading of the existing scientific literature. The summaries were presented to a Jury, also called multidisciplinary Consensus Panel, who drafted a series of recommendations. RESULTS: The prevalence of HPV in males ranges between 1.3-72.9%;. The prevalence curve in males is much higher than that in females and does not tend to decline with age. Women appear to have a higher probability of acquiring HPV genotypes associated with a high oncogenic risk, whereas in males the probability of acquiring low- or high-risk genotypes is similar. The HPV-related diseases that affect males are anogenital warts and cancers of the penis, anus and oropharynx. The quadrivalent vaccine against HPV has proved to be effective in preventing external genital lesions in males aged 16-26 years in 90.4%; (95%; CI: 69.2-98.1) of cases. It has also proved to be effective in preventing precancerous anal lesions in 77.5%; (95%; CI: 39.6-93.3) of cases in a per-protocol analysis and in 91.7%; (95%; CI: 44.6-99.8) of cases in a post-hoc analysis. Early ecological studies demonstrate reduction of genital warts in vaccinated females and some herd immunity in males when vaccine coverage is high, although males who have sex with males gained no benefit at all. Males with an immunodeficiency disease are at greater risk of developing disease. Infertility seems to be caused by HPV in some cases. Studies demonstrate vaccination to both genders can be more efficacious and social equity matters are to be taken into consideration. CONCLUSIONS: The Jury made Recommendations based on the scientific evidence presented by the Scientific Committee. Accordingly, for prevention purposes and social fairness and equality, as both sexes are affected by the disease, the vaccination of 12-year-old males against HPV should be recommended in order to guaranty protection to everyone. Aspects related to healthcare policy and economic sustainability, are to be discussed by respective public system representatives. More campaigns to raise awareness through all institutional channels are needed, not only regarding anogenital warts, but for HPV-related diseases in general in males in accordance to new scientific evidences
